"I-I'll..." Haku swallowed hard, trying to calm her own frayed nerves for Miku's sake. "I'll explain when you're out!"

Not that there was much to explain. No one really knew WHY they were there.

"J... just..."

She fumbled around the edge of the lid. Unlike her own stone tomb that had fallen from the ledge and broken open, Miku's seemed set properly in place and unmoving as any of the others, which meant the lid would have to be pulled aside.

Her fingers hooked in to the tiny gap between lid and back, robotic arms pulling with all their strength. She groaned and grunted, and had she been human a sweat would have broken out on her brow.

But it only budged enough for there to be a wider crack, and soon enough Haku fell back on her rear with the exertion of it.

"Uwaah..." she whined, rubbing her lower back.
